bringing up bobbin thread question

This is a repeat of another question I had on my original hiding bobbins question. Sorry for the repeat. Well here is another question I have. I know how to bring up the bobbin thread before beginning a line of quilting.

How do you bring up the bobbin thread when you end a line of quilting (assuming I am going to tack it down on stitch length 0, and not bury the threads in the batting)? Do I tack it down, then use the atuo thread cutter to pull up the bobbin thread? And if I wanted to hide the threads, would I have to move the fabric over a couple inches (before auto cutting it)so the bobbin thread has some length in order to pull it up, knot it with the top thread, then bury it?

I don't use the thread cutter when machine quilting. If I understand your questions:

If you tie the end of the quilting by using very small stitches (0) and moving the stich back and forth or round a bit
then you don't need to bring the bobbin thread up. You will only need to bring bobbin thread up if you intend to bury the tails in the batting.
When I am quilting a straight line and come to the end, I will usuall just hit the back stich and let it go a couple stitches, remove the piece with a long tail and no bringing up is necessary. Now if you are quilting to the edge and going to attach binding, I usually forget to do the very small stitches or back stitch. In these cases I may go back and put a dab of Fray Chek on the ends to make sure they stay in and will be covered by the binding.
Now. Now if I am quilting a long line within the quilt I will always leave a long tail and bury the threads. I don't worry about pulling the bobbin thread up but will do that when I get ready to bury the ends. In these cases I don't do a back stitch or the tie stitch on the machine as double stitching will usually be noticed (by me) and probably leave a darker dot on the quilt.
Hope this answers some of your questions.

I just feel that I have better control to use scissors to cut the threads. Also I have read and heard that it is not good idea to use the thread cutter when machine quilting as it doesn't leave enough tail to bury or tie off.
Also, on some of my machines when using the tie tack stitch it will put a knot on the top and I usually accidently cut this off when I am trimming the end thread and loose the secure end of the quilting.

I cut both top and bobbin thread and leave long tails. I don't use the machine auto cutter. Then pull on the top thread and a tiny loop of the bobbin thread will pop up. Stick a pin thru that loop and pull.

You might be able to use the LA trick: before you take a stitch put a length of the upper thread and stitch over [not in] it ... or pull out extra t op thread and keep it in your fingers ... then pull up with the sew over upper thread and the upper thread from the needle. That will make it so you can pull up the bobbin thread.

If you want to pull up the bobbin thread at the end of stitching, follow this.
Lift your pressor foot (to release the thread) and move your quilt over about 4" - this makes the length of thread.
Then put the foot down and hit the thread cutter -if you have one.
Tug on the upper thread and watch the last stitch you made to see the bobbin thread pull up, lift it with a needle and pull to the top. Once you get the system - it's easy.
It's also helpful to make sure when you stop stitching, that you make one more single stitch. Don't stop when you're making back tacking or tiny stitches or it will be hard to see the loop of bobbin thread to pull up.
